Be'it-known thatJLQEARL T. PHELAN, citizen of the llnited States, residing-at Jackson, in the county of Jackson and State certain new and useful Improvements in Cushion-Rims, which the following is a specification.

This invention relates to an. improved cushion rim for vehicle-.wheels and has as one. of its principal objects to provide va device of this character'which may be em ployed in connection withthe'wheels of motor vehicles for supplanting the ordinary pneumatic tire. i

rovide a rim employing resilient cushion-f mg blocks andwherein'theprinciple ofa toggle will be embraced in conjunction with said blocks whereby a maximuml cushioning had from the blocks. A still furtherjobject of the invention is to provide a rim employing .aplurality of toggle. members between. the ,cushioning blocks and wherein said members may be adjusted. for varying thef,normal;.rigidity of the rim.

'And-theinvention .has'as a still further object to provide a grimwliichgmay be read.-

the channel-of the inner band 10 is an an nular series of spaced cushioning blocks 14 and seated in the channel of the outer band 11 is a similar series of cushioning blocks 15, theblocks of the series being staggered. Extending. between the .flanges of. the respective bands at opposite sides of each of the blocks are stop rods 15- securing the blocks against creeping. The cushioning blocks are of similar construction and in Figs. 5 and 6, I have shown one of said blocksin detail. As there illustrated, each of said .blocks is formed with a base from whichrises amedial" semi cylindr'ical rib 16 extending longitudinally of, the base from endto end thereof. Base flanges 17 are thus defined at opposite sides of the rib and, as will be observed, the side faces of the rib merge'with the upper faces .ofsaid'flanges bearingsseats .18 at the junctions between said rib and'flanges while the side faces block.

The, bearing shownin 2, ve rsely 'iof the rim.

therein and bearing blocks are, as particularly arranged to extendtransbands fitting snugly between the series of blocks is a plurality of togglemembers. In

have shown F igs.f3 and 4: of the drawings I oneof said members in detail. As will be observed, each of ;the toggle members is formed of inner and outer sections. -The inner section comprises a cross head 21 havl .ing merging convex and concave bearing faces 22 and 23 respectlvely and rislngfrom the base of the head at a point subbetween its ends, is a Extending from the direction opposite to said stud are spaced parallel posts 25 suitably secured tothe. head. and disposed adcentering a stud 24.

of the rib provide convex bearin g seats 19 abovethe first seats. Formed. in opposite sides of the block at the base of. -,-the.' rib are "inclined sockets 20 located subbetween the-ends of the] jacent opposite endsther'eof. .Like the inner section, the outer section of each of said toggle members is formed with a cross having merging convex and concave bearing faces 27 and 28 respectively, and rising'from thebase of the head at a point substantially midway between its ends is a centering lu'g 29'similar to theglug 24.

i Extending from the 5 end portions of "the head in; a direction opposite to sa d lug .28 of the heads engage the seats 19 of the r are spaced parallel sleeves 3O whichfreely receivethe posts 25 of the inner section and threaded upon said postsv to coact with the sleeves are adjusting nuts 31. Attention is now directed to the fact, as particularly shown in Fig. 4, that the sections of each of the toggle membersare assembled soithat' the cross heads 21 and 26 are reversely directed. Consequently, the toggle members maybe assembled with the cushioning blocks '14: and 15 to bear therebetween in the manner shown in Fig, 1. As'Willbe observed", the studs 24' of the cross heads 21 are fitted{inthe 'sockets 20 of the inner series of blocks 14 while the studs 29 of the cross heads 26 are engaged in the sockets of the outer series of blocks, these studs being provided with beveled end faces to prevent gouging of the blocks. The cros'sl heads will thus be supportedupon the blocks so that the j convex, faces 22 and 27v ofsaid heads wiillengage in the seats 18 of the blocks while the concave faces '23 and blocks. Theftoggle members will accordngly co'act with the blocks for centering served,1]as bestfjshown in Fig; 1, that When the inner band oves; downwardly ineccen trio'relationto the outer band, the toggle membersat the upper and lower side portions offthe rimwilfbe' rocked toward ialined' position so that the convex bearing faces o'f saidmembers will press into the concave seats ofthe blocks, the toggle mem-' bers thus tending to compress-the blocks: therebetween. On the other hand, theconcave faces of the cross heads'of the togglemembers will coact-with" the convex seats of the ribs 16 of the blocks for resistingre bound of the inner rim band; Thus, the arrangement shown, a maximum cushiomng efie'ct will be obtained from the blocks. 50

' of'the toggle members will. c'oact with-the Further, as will be observed, the cross heads blocks for cushioning lateral shock or strain upon the rim. By simply adjusting the nuts 31 ofithe toggle membersto vary the effective length thereof, the normal rigidity of'the rim.,1 nay,-as willbe at. once appreciated, be inturn'varied. so that the rim may accordingly be easily adapted for use upon vehicles of different weights. Further, by

this-adjustment 'o f'the toggle members, a

maximumv cushioning efi'ect may be obtained from the rim 1 for any particular vehicle; Loosely fitted; upon theposts 25 of each of the toggle members isfa locking strip'Sl' extending transversely between said "posts is claimed as newi s'z and the ends of which are-bent li id-0011f front thenuts Sl for thus locking 'said nuts in adiustedposition; 4 In the rawings, I have shown my improved rim in connection with, a conven- 'tionaltype of motor vehicle wheel 32 providedwith a felly bands33 and eq-ui-pped with clamping bolts 35 carrying wedges 36.

As will be seen, therim of the presentinvention may, like an ordinary demountable.

rim, be slipped overthefe'llyb'and'of the wheel to coact therewith WhenQafter the wedges have been. properly'positioned'in the manner shown in F ig. 2, the nuts" of the clamping bolts mav' be adjusted for tightlybindingthe rim in place Accord ingly, the rim of the presentin vent'ion may be readily used in connection withjthe large percentage" of motor vehicles atpresent equipped to reeeivedemountable wheel rims. However, I do not Wish to be-limi-ted in, this regard since, as will-be seen," the rim band 10 maybe applied directly 'toa wheel felly for displacingtheusual felly band and per-' manently connecting the rim with-the wheel.

I accordingly reserve the right to all such; adaptations of the inventionas; may fall within the spirit of the appended claims.
